An account in Val-de-Marne, France

On June 8, 2015 at 2:30 a.m., a witness observes, through a roof window, about 10 reddish-orange luminous points moving silently in a straight line in the night sky. The points disappear gradually. Only one testimony is collected. The observation of reddish-orange luminous points crossing the sky in less than a minute, on a weekend night, clearly suggests Thai lanterns, probably released nearby at the end of a private party. The arrival and gradual disappearance of the lights is fairly characteristic of these objects launched in sequence, with a lifespan of a few minutes (depending on the burner). The movement is observed from East to South, which is consistent with the Northwest to North-North wind recorded at Neuilly-sur-Marne (see the Infoclimat record at Roissy, 20 km away: a slight Northwest wind is noted). The GEIPAN classifies this case "B": probable observation of Thai lanterns.
